Re: [Samba] RPC and NDR errors in log file




Hai, 

Based on : IsSigneddnsserver: Invalid zone operation  

Are you running against a ( forwarded ) DNSSEC server or DNS Crypt server. 
Try an other forward if are.

If you running internal samba DNS, try bind9_DLZ 

Handy list for dnssec and dns crypt:
